" (v) "(a-b)(a+b)+(b-c)(b+c)+(c-a)(c+a)=0

Show that: (a-b)(a+b)+ (b-c) (b+c) +(c-a) (c+a) =0

Show that (a-b)(a+b)+(b-c)(b+c)+(c-a)(c+a) =0

Show that : (4p q+3q)^2-(4q p-3q)^2=48 p q^2 (a-b)(a+b)+(b-c)(b+c)+(c-a)(c+a)=0

Show that : (4pq+3q)^(2)-(4qp-3q)^(2)=48pq^(2)(a-b)(a+b)+(b-c)(b+c)+(c-a)(c+a)=0

If in a triangle A B C angle B=90^0 then tan^2(A/2) is (b-c)/a (b) (b-c)/(b+c) (c) (b+c)/(b-c) (d) (b+c)/a

If in a triangle A B C angle B=90^0 then tan^2(A/2) is (b-c)/a (b) (b-c)/(b+c) (c) (b+c)/(b-c) (d) (b+c)/a

Show that: (a – b) (a + b) + (b – c) (b + c) + (c – a) (c + a) = 0

If (a+b-c)/(a+ b) =(b+c-a)/(b+c) = (c+a-b)/(c+a) and a+b+cne 0, then prove that a = b = c.

(a+b-c)/(a+b)=(b+c-a)/(b+c)=(c+a-b)/(c+a),a+b+c!=0 find relation

If a+b+c=0 , then the value of ((a+b)/(c)+(b+c)/(a)+(c+a)/(b)) ((a)/(b+c)+(b)/(c+a)+(c)/(a+b)) is
